Abstract

The invention relates to a metal surface enamel layer, processing technology of an interface thereof and the use of the technology. The metal enamel has a high sintering temperature and short time which is within 3 to 8 minutes; and the conventional sintering process has difficulties in realizing the metal enamel and requires high cost. The processing technology comprises surface processing and enamel processing, wherein in the surface processing, surfaces of metal material products are processed by adopting electric arc spraying or oxyacetylene spraying; and in the enamel processing, an electric induction heating method is adopted for high-temperature sintering at the temperature of between 850 and 1,100 DEG C for 3 to 8 minutes. The processing technology is applied to enamel products of the surfaces of metal materials.

Description

Technical field:

[0001] The invention relates to an interface treatment technology of metal surface enamel. Background technique:

[0002] At present, enamel tubes, enamel steel plates, enamel heat exchangers, radiators and other metal matrix enamel products have excellent wear resistance, corrosion resistance and high temperature resistance. However, the bonding strength of the enamel layer of these products is not high, and the enamel layer is easy to fall off under impact, which seriously affects the performance of the enamel layer. Therefore, improving the bonding strength between the enamel layer and the metal matrix material is the key to obtaining excellent performance of metal enamel products.

[0003] At present, the sintering of enamel products on the surface of metal substrates is limited to small-sized and light-weight parts. Generally, coal, coke, and resistance furnace sintering process are adopted in the city. Overweight and overlength products cannot be si...
